I have used SweatBlock for the last two years. It has changed my life. I don't have nervous sweat any longer. It started working immediately. It is the greatest product I have ever used to deal with sweat. I have tried every over-the-counter product and nothing would work. I have just started using the SweatBlock spray deodorant in the last few weeks and it is incredible too. It only takes a small spray and it controls odor all day. I just ordered the SweatBlock deodorant stick for the first time and I'm waiting for it to arrive. I love these products and I highly recommend them.
